The Nationals swapped Harper with Soto so I wouldn’t say they lacked star power. That’s not including Scherzer, Strasburg, Turner, Rendon and Zimmerman. The 2015 Royals are the last team that comes to mind that didn’t feature any real star talent.
Outside of the 2023 Rangers who still rode the bat of their $300 million World Series MVP Corey Seager, catching lightening in a bottle with a bunch of scrappy guys like the 2005 whitesox or 2015 Royals is rare and will always remain that way.
